Lesson 7

Question 1

Evidence for evolution comes from many different areas of biology: Anatomy.

Answer 1

Evidence of Evolution

Question 2

4 Major Categories of Evidence for Evolution

Answer 2

• Fossil Evidence
• Anatomical Evidence
• Embryological Evidence
• Biochemical Evidence

Question 3

All the fossils ever discovered on earth make up the fossil record

Answer 3

Fossil Record

Question 4

Method of measuring age of object in years

Answer 4

Absolute Dating

Question 5

• Involves comparing the body structures of species
• Is the study of differences and similarities in the anatomy of different species

Answer 5

Comparative Anatomy

Question 6

Are structures that are similar in function with different structural compositions. They have a different ancestral origin and hence do not have a shared common ancestor

Answer 6

Analogous Structures

Question 7

Are similar physical features in organisms that share a common ancestor, but the features serve completely different functions. An example of homologous structures are the limbs of humans, cats, whales, and bats.

Answer 7

Homologous Structures

Question 8

• Features present in modern animals that are no longer in use
• Give hints as to the evolution of organisms

Answer 8

Vestigal Structures

Question 9

• Comparing embryonic development of different animals helps determine evolutionary relationships in nature

Answer 9

Embryological Evidence for Evolution

Question 10

The study of where organisms live now and where they and their ancestors lived before in the past

Answer 10

Biogeography

Question 11

• Common ancestry can be seen in the complex metabolic molecules that many different organisms share.
• Comparison of the DNA or RNA of different species produce biochemical evidence for evolution

Answer 11

Biochemical Evidence
